A question, I know people are mostly on a satellite dish or cable these, days but the few are still on an Arial that like the BBC Can, A Standard CB on 4 watts cause TVI ? I remember back in the days of CB/81 there where problems with this issue.

Not a problem much today with the modern tv's we have. 3 years back i had a silver-rod directly in front of out tv aerial and no problems or with the houses around me.

As Alan Pilot said in the last post,TVI isn’t really an issue with today’s Satellite systems and TV now being Digital and not analogue beamed from Crystal Palace.The only complaint I did get once was from the kids saying they could hear my voice while I was on AM Mode through their Nintendo switch headsets.(No doubt me being overzealous with the output) What I did just for peace of mind was add a RM 27/586 Low pass filter inline just to stop any bleed over or double harmonics.Which works well over 30mhz and have yet to have any neighbour knocking on my door. Also 4 Watts QRP I wouldn’t even worry,Hope my waffling helped. Cheers Tom.

On my 9900 with Sirio 4000 parked next to my caravan I interfere with. My TV running through a satellite dish facing away from my antenna. A neighbouring caravan using a tv aerial on digital. And another neighbour watching netflix etc via internet
If it still interferes when I put up a dipole I'll buy a tvi filter.

Not sure, definitely does at full chat, but I think it still does it when the power is dialled down.
I'll experiment next time I'm away. I'm hoping the dipole being higher up will eliminate it
